Abstract
The utility model relates to an elastic seal device for a marine gearbox bearing, in particular to an oil seal ring used on an output spindle of a gearbox. The elastic seal device for the marine gearbox bearing comprises the gearbox, the output spindle and an annular seal ring, wherein the gearbox is provided with the output spindle, and the annular seal ring is arranged on the output spindle. The elastic seal device for the marine gearbox bearing is characterized by further comprises a spring ring, three annular grooves are formed in an inner face of the seal ring, an annular spring groove is formed in an outer face of the seal ring, and the spring ring is embedded in the spring groove. The elastic seal device for the marine gearbox bearing has the advantages that sealing performance of the bearing during working processes of the output spindle of the gearbox is better, oil leakage is reduced, and the spindle is protected from damage since a polyimide material is adopted.
Description
Technical field
The utility model relates to a kind of marine gear axle box bearing elastic sealing device, particularly a kind of oil seal circle being used on gear-box output main bearing.
Background technique
In marine gearbox inside, need to there is lubricant oil to be lubricated, lubricant oil in gear-box leaks in cabin or causes the pollution of river from spindle nose, therefore, just very crucial to the sealing of lubricant oil in gear-box, sealing means has multiple pattern, and traditional ring structure is simple, shortcoming is that sealing effect is poor, the easy slippage of seal ring, lacks limit structure, and cannot adjust after ring wear.
Model utility content
The purpose of this utility model is to overcome existing the problems referred to above in prior art, and provides a kind of reasonable in design, the marine gear axle box bearing elastic sealing device of good sealing effect.
The utility model solves the problems of the technologies described above adopted technological scheme: this marine gear axle box bearing elastic sealing device, comprise gear-box, output main shaft and O-ring seal, described gear-box is provided with output main shaft, output main shaft is provided with O-ring seal, it is characterized in that, also include spring ring, on the inner side circle face of described seal ring, have three road annular grooves, on the outside circle face of seal ring, have annular spring groove, described spring ring is nested in spring groove, on described seal ring, be fixed with limit convex, described gear-box is provided with restraining groove.Spring ring can tighten up seal ring, thereby improving product is for the laminating degree of bearing, strengthen sealing effect, in order to prevent that elastic seal ring is along with output main shaft together rotates, on the gear-box coordinating with elastic seal ring, be provided with restraining groove, limit convex on elastic seal ring is just in time placed in one, and reaches the object that prevents rotation.
As preferably, the bottom of described annular groove is round slip surface.
As preferably, described seal ring is annulus circle.
As preferably, described seal ring is polyimide material, is a kind of organic polymer high-abrasive material.
The beneficial effects of the utility model are: the sealability of bearing is better in the course of the work to make gear-box output main shaft, reduces leakage of oil, adopts polyimide material can not damage main shaft simultaneously.
